I presume yours is flat so you should only need to start at much higher numbers. But I'm no expert so I have no idea where you should start. Obviously the higher you start the less you have to do to get the gloss finish.
Wet sand with water and a drop or two of washing up liquid. Don't press too hard as the paper will gum up really quickly. You'll probably have to clean the paper after a minute or so anyway. Try and do long gentle strokes.
After I got to 2000 the surface was still slightly matte. You will then need to go to a cutting compound. Something from an auto shop should do. Being a cheapskate and a rebel I just used whatever I have in the house , and that happened to be Brasso. I then used some Scratch X 2.0, but to be honest I didn't see any improvement over the Brasso.
Here's how the fingerboard turned out.
